Upgrade Ext3 File System To Ext4 File System In Jaunty

Most of you have installed Jaunty by now. Some might have decided to experiment with the bleeding edge Ext4 which offers benefits:

The biggest advantage to ext4 is the support for larger volumes (up to 1 exabyte) and larger files (16 terabytes). There are other improvements that ext4 regarding allocation. Both pre-allocation and delayed allocation have been added. These improvements deal with how space is allocated for files. The former will boost performance for systems like streaming media and databases. The latter will improve fragmentation.

To those of you regretting not enabling Ext4 here is how you can convert your Ext3 into Ext4 without reinstalling.
